IPC: C07C17/38
Filed: 1994-11-25
Abstract: Volatile organic compounds and water vapor are recovered from a low-boiling gas by compressing the gas to an elevated pressure and cooling the gas in stages to condense volatile components and water while avoiding freezing in the system. Operating the system at an elevated pressure increases condensation efficiency, reduces the number of stages required, and minimizes operating problems to avoid freezing.

Abstract: A rectal administrator comprises a body having an administrative portion adapted to be inserted into a subject's rectum. A charge of medicament is disposed within the body, and the administrative portion has at least one passage through which the medicament can exit the body. A plunger is disposed in the body and is movable from a first position to a second position within the body to dispense the medicament from the body through the at least one passage. A releasable energy source is mounted within the body so as to be released in response to a predetermined actuating procedure. The releasable energy source moves the plunger from the first position to the second position to dispense the medicament from the body through the at least one passage when released in response to the predetermined actuating procedure.

Abstract: A load cell for sensing weight and torque on a drill bit during a drilling operation includes a cylindrical load cell made from a material with minimum residual stress. A plurality of strain gauges are arranged symmetrically on each load cell and electrically coupled to form two Wheatstone bridges. The load cells are mounted 180 degrees apart in radial pockets drilled in a drill collar wall. A half Wheatstone bridge from one load cell is electrically coupled with a half Wheatstone bridge from the other load cell to form a Wheatstone bridge for measuring WOB and a similar coupling is made to form another Wheatstone bridge for measuring TOB. In another embodiment, additional strain gauges in another Wheatstone bridge measure differential pressure. The output of the pressure and weight bridges are electrically combined to provide a weight signal unaffected by differential pressure fluctuations. The load cells are force fit in the radial pockets in the drill collar and a cap is installed on each pocket housing a load cell to protect the load cell from drilling fluid. The strain gauges in each load cell are placed to minimize the effects of bending, hydrostatic pressure, temperature, differential pressure and cross talk between WOB and TOB measurements. The load cells can be replaced easily and drill collar gauging is not required. Since the strain gauges are not directly attached to the drill collar, the high residual stress in the drill collar does not cause the strain gauges to drift.

Abstract: A compact print making device by which a desired imprint figure can be made easily in a short time. This print making device employs a resin seal face member, a part of which receives light having a wavelength within a predetermined range and thus is put into a state different from the state of the remaining part thereof and is adapted to have an uneven face formed by being acted upon by a predetermined fluid. The resin seal face member and an original picture representing an imprint figure are placed in such a manner that the original picture is placed just in back of the resin seal face member. Imprint figure information representing the imprint figure shown in the original picture is taken in by an information reading mechanism. A negative film making unit is driven according to the imprint figure information so as to produce a negative film. Then, the produced negative film is carried to an irradiating position. Subsequently, a light irradiating unit irradiates the resin seal face member with light through the negative film. Thereby, the state of a part, which corresponds to the imprint figure, of the resin seal face member or the remaining part thereof is changed. Finally, an uneven face thereof serving as a seal is formed by acting a predetermined fluid upon this resin seal face member.

Abstract: Semiconductor diode lasers are used  inter alia  in optical disc systems, laser printers, bar code readers, and glass fibre communication systems. Lasers having a so-called (weakly) index-guided structure are very suitable for many applications  inter alia  because they can be manufactured comparatively simply and reliably. 
     A disadvantage of the known (weakly) index-guided laser is that the so-called P-I (= optical power-current) characteristic thereof exhibits a kink. Such a kink limits the use of the laser to a relatively low optical power. 
     According to the invention, such a (weakly) index-guided laser has a resonance cavity with a length for which the optical power at which a kink occurs in the P-I characteristic is a maximum. It was a surprise to find that the occurrence of a kink in the P-I curve of such a (weakly) index-guided laser depends on the length of the resonance cavity. Very surprising is the appearance of a maximum value in this kink power as a function of the length of the resonance cavity. 
     Equally surprising is the occurrence of a series of such maxima, which are substantially equally high, and which are formed by the crests of a sawtooth curve with a very steep flank at the rising edge to each maximum. As a result, the laser length may be optimized not only in relation to the occurrence of kinks in the P-I characteristic but also in relation to other properties. The invention also relates to a method of manufacturing a laser according to the invention, which preferably comprises a ridge waveguide structure.

Abstract: Disclosed are a printing apparatus and a method of initializing it which allow to prevent loss of print data due to print operation malfunction after the completion of the initialization. This is achieved by detecting error conditions related to the motion of a print head during the initialization. In the initialization process of the print head (3) is moved until it is detected by a reference position detector (16) located at the left edge of a printable area. Then the print head (3) is moved over the entire printable area to its rightmost position (37). By checking whether or not the print head has moved correctly, it is possible to detect any error conditions relating to the motion of print head (3) prior to printing.

Abstract: Downsampling and inverse motion compensation are performed on compressed domain representations for video. By directly manipulating the compressed domain representation instead of the spatial domain representation, computational complexity is significantly reduced. For downsampling, the compressed stream is processed in the compressed (DCT) domain without explicit decompression and spatial domain downsampling so that the resulting compressed stream corresponds to a scaled down image, ensuring that the resulting compressed stream conforms to the standard syntax of 8 x 8 DCT matrices. For typical data sets, this approach of downsampling in the compressed domain results in computation savings around 80 % compared with traditional spatial domain methods for downsampling from compressed data. For inverse motion compensation, motion compensated compressed video is converted into a sequence of DCT domain blocks corresponding to the spatial domain blocks in the current picture alone. By performing inverse motion compensation directly in the compressed domain, the reduction in computation complexity is around 68 % compared with traditional spatial domain methods for inverse motion compensation from compressed data. The techniques for downsampling and inverse motion compensation can be used in a variety of applications, such as multipoint video conferencing and video editing.

Abstract: In a system that uses inter-frame coding to compress
blocks of data for transmission from a transmitting device
to a receiving device, and sends acknowledgment signal back
from the receiving device to the transmitting device, the
receiving device packs decoding-error information about
multiple blocks into each acknowledgment signal. The
transmitting device unpacks the acknowledgment signal to
obtain the decoding-error information, and uses this
information to keep from performing inter-frame coding with
reference to data that the receiving device was unable to
decode. The bandwidth saved by packing information about
multiple blocks into each acknowledgment signal can be used
to enhance reliability by repeating the information in
multiple acknowledgment signals.
